Abstract

A head restraint positioning device is provided for a head restraint of a vehicle seat. The head restraint positioning device includes an impact device movably connected to the head restraint and arranged on a seat back of the vehicle seat in the area of a pelvis of a passenger sitting on the vehicle seat. The impact device includes at least one structural unit that varies in length in response to the application of pressure and that causes a corresponding change in length of the impact device to change the position of the head restraint.
